WILLIAM I-I. HOLLAR, WALTER BEES. AND HARRY F. BALUQMOF PHILADELPHIA, PENNSYLVANIA; SAID BEES AND BALOU ASSIGNORS TO SAID I-IOLLAR.

VA'ULT.

To all whom it may concer/n:

Be it known that we, WILLIAM I-I. I-IoLLAR, WALTER Rans, and HARRY F. BALoU, of Philadelphia, in the State of Pennsylvania, have invented a certain new and useful Improvement in Vaults, whereof the following is aV speciiication, reference being had to the accompanying drawings. j

Our invention relates to vaults having sectional walls formed of separable metal plates assembled in alinement and detachably connected, and is particularly applicable to such ceiling walls. Hitherto, it has been the practice to support such walls by metal beams having bolts or other separate attaching means `connecting them! with the walls, and to connect the wall plates at their joints by bolts or other separate attaching means distinct from the means employed for attaching said beams.

It is the object of our invention to lessen the number of holes or socket-s for attaching means which must be formed in the plates, by utilizing the same bolts to connect the wall plates with each other and with the beams, and in such manner that such attaching means are inaccessible from the exterior of the vault, and the outer faces of the wall plates are imperforate.

As hereinafter described, our invention comprises such a construction and arrangement that the supporting beams are engaged with the plates by projections on the beams f extending in recesses in the adjacent edges of the plates and the latter are' connected in the desired relation with the beams by bolts which are inaccessible from the eX- terior of the vault. Such construction is particularly advantageous in its adaptation to vault walls made of armor plate, which are weakened by the ordinary methods of connection of the plates with their supports, because of the necessary softening ofthe exterior of the plates incident to the formation of the holes or sockets for the ordinary attaching means, it being observed that the improved construction does not require any holes or sockets in the outer faces'of said plates which may therefore remain of their original hardness. Y

Our invention comprises the various novel features of construction and arrangement Specification of Letters Patent.

hereinafter more vdefinitely specied.

In the drawings; Figure I, is a longitudinal sectional view of a vault conveniently embodying our improvement, section being taken on the line I, I in Fig. II. Fig. II, is a vertical transverse sectional view of said Arana ori-rien. f V

vault, taken on the line II, II in Fig. I. f

Fig. III, is a fragmentary sectional view showing the form of the inventionV indicated in Fig. I, but on a larger scale. Figs. IV,

14, and front wall 15, the latter being conveniently formed of armor plate substantially in alinement with said building wall`3. As shown in Figs. I and II, the ceiling wall 11, is supported byftransversely extending beams yincluding vertical webs 18, Lhavl ing their respectively opposite ends supported in said building walls 3 and 4, and

having shoulders 19, overlapping the contiguous edges of the adjacent plates of which said ceilin 11, is formed. Said beams and plates are interengagedby projecting ledges 20, upon respectively opposite sides of said beams extending in corresponding undercut recesses 21, in the edges of said plates.

As shown in Fig. III, the margins 22 "l and 23,`of said plates are overlapped, and said plates are fastened together by the screw bolts 2li, having their heads counter-y fao sunk in the plate margins 22, and their opposite ends in threaded engagement with sockets 25, in said plate` margins 23, and

said fastening means also serve to rigidly connect said beams 18, with said plates withoutthe employment yof any additional fastening means, said beams being thus held i with their .projecting ledges 20, in engagementwith the recesses 21, and with their webs extending from said plates exteriorto the vault inclosure.

Referring to Fig. II, it may be observed ioo that said projections 20, terminate shortof*` the ends of the beams 18, and the latter rest upon plates 27, inrthe respective supporting walls. Said beams are also conveniently provided with bra cliets 29, rigidly connected therewith, and resting upon the tops of the plates 11, so as to brace said beams 18, in normal relation to said plates. IVe also tind it convenient to embed said beams in masses oit concrete 30, reinforced by rods 31, in connection with the opposite walls ot' the building.

The t'orm ot our invention shown in F ig. IV, differs from that shown in I? ig. III, only in that theoppositely projecting le( ges 3%, converge toward the shoulders on the beam. It may be observed that tight joints may be made between the plates and beams in this form of our invention without the accurate fitting required for the form shown in F ig. III.

It being noted that in both of the forms of our invention shown in Figs. III and IV, the adjacent edges ot' the adjoining plates must be dilicrently shaped; it is to be understood that it is within the scope o;t` our invention to connect the supporting beams with plates having recessed edges which are precisely alike. For instance, as shown in Figs. V and VI.

In the form of our invention shown in Fig. V, the beam comprising the vertical web 3S, having shoulders Si), overlapping the adjoining plates t0. has projecting ledges all, engaging' similar undercut recesses ft2, in said plates, and also overlapping the margins I-3, thereof, so as to be conveniently connected therewith by the screw bolts ta, which extend through said ledges 41, in screw threaded engagement with sockets AIG. in said plates.

In the form ot' our invention shown in It VI, the beam comprising the web 4S, has opposite projections 50. engaging corresponding recesses 51, in the edges ot the adjoining plates 52. and said beam and plates are retained in engaged relation by the plate 53. which overlaps the margins 54. oit said plates 52, and is connected theren with b v the screw bolts 55, which extend through said plate in screw threaded engagemelitwith the sockets 56, in said plates 52.

It may be observed that it is characteristic of all ot the forms ot' our invention above described, that the beams are engaged with the plates by projections extending within recesses in the edges of the adjoining plates, and without the employment ot any connecting means accessible from the exterior ot the vault. so that the outer races ot' the wall plates may retain tne maximum degree of hardness and consequent resistanceto attack, which is not the case in structures requiring pertorations or sockets in the outer faces of the plates 'for the engagement ot the attaching or supporting means.

IVe do not desire to limit ourselves to the precise details of construction herein set forth, as it is obvious that various moditications may be made therein without de parting trom the essential features ot our invention as defined in the appended claims.
